Best and Worst Mercedes-Benz C300 Years: What the NHTSA Data Shows

Across the 13 Mercedes-Benz C300 model years from 2010 to 2022 that have NHTSA data, the typical year has about 284 owner complaints on file. These are the extremes:

Fewest owner complaints

  • 2021 — 15 complaints, 0 recall campaigns, 5★ NHTSA
  • 2022 — 26 complaints, 0 recall campaigns
  • 2020 — 46 complaints, 0 recall campaigns

Most owner complaints

  • 2012 — 587 complaints, 0 recall campaigns
  • 2013 — 574 complaints, 0 recall campaigns, 5★ NHTSA
  • 2011 — 516 complaints, 0 recall campaigns, 4★ NHTSA

Complaint counts are unverified owner reports to NHTSA and rise with how many cars were sold and how long they have been on the road, so treat them as a pointer for what to inspect, not a reliability score. Model years after 2022 are left out because they have had little time to accumulate reports. Always check a specific car by VIN at nhtsa.gov/recalls.
